Quick blueberry oatmeal muffins are full of wholesome whole-grain oats and berries and they’re so easy to whip up in one bowl. The batter is dairy-free and can be made with gluten-free flour. Make a batch to start off the day or pack into a lunchbox for a healthful snack.

Even if you’re a minimalist when it comes to baking, you probably have all the ingredients on hand to bake a quick batch of these blueberry oatmeal muffins. They’re dairy-free, with a tender texture. Plus, they are absolutely loaded with juicy blueberries and whole grain oats.

The recipe couldn’t be easier — the batter mixes up in minutes. If you have one bowl and a mixing spoon you’ll be good to go!

Ingredients in homemade blueberry oatmeal muffins

  • Oatmeal: I tested these muffins with whole rolled oats and quick oats. Either type will work.
  • Flour: All-purpose flour or a gluten-free all purpose blend will work in this recipe. You can also swap about 1/2 cup of the all-purpose for whole wheat flour.
  • Blueberries: You’ll need one pint of fresh blueberries or 2 cups frozen berries (Just measure them out and let them thaw for about 15 minutes, then drain the liquid).
  • Sugar: The muffin batter is lightly sweetened with granulated sugar, then topped with sparkling flakes of turbinado sugar (also called “raw” sugar) that offer a pleasant crunch every time you take bite. Brown sugar or coconut sugar are good substitutes for the turbinado.
  • Oil: Use a neural-tasting oil, such as canola, avocado or sunflower.
  • Optional flavor add-ins: Stir in one teaspoon of vanilla extract, fresh lemon zest or ground cinnamon into the batter along with the other dry ingredients.

A quick breakfast for me usually means a bowl of oatmeal or a batch of these blueberry oat muffins — mostly because they don’t require much fussing to make on a groggy morning.

When you’re in the mood for a wholesome whole grain muffin that tastes pure and simple, this is a great recipe to turn to.

Not to say that every once in a while a slightly more decadent jumbo bakery-style blueberry streusel muffin or stack of whole grain buckwheat pancakes is out of the question!

Step by step instructions

By the time the people in your house wake up, these blueberry muffins will be warm from the oven and ready to eat. Enjoy!

Servings 12 muffins


  • ½ cup (50 g) whole rolled oats or quick oats
  • ½ cup (125 ml) orange juice, milk (dairy or plant-based) or water
  • cups (205 g) unbleached all-purpose flour or gluten-free flour blend
  • ½ cup (100 g) granulated sugar
  • 1 ¼ teaspoons baking powder
  • ½ teaspoon salt
  • ¼ teaspoon baking soda
  • ½ cup (125 ml) neutral oil, (such as canola or sunflower)
  • 1 egg, slightly beaten
  • 1 pint (260 g) fresh blueberries, or 2 cups frozen blueberries, thawed and drained
  • 1½-2 tablespoons raw turbinado sugar, or coconut sugar
  • ½ teaspoon ground cinnamon, optional


  • Preheat oven to 425 (220 C) degrees.
  • In a large bowl, combine oats with the liquid (juice, milk or water.) Let sit 5-10 minutes.
  • Add flour, sugar, baking powder, salt, baking soda, oil and egg and mix well. Gently fold in the blueberries.
  • Divide the batter evenly into 12 paper baking cups or oiled muffin tin.  Sprinkle the sugar and cinnamon (if using) over the top of the batter.
  • Bake 16-21 minutes, until tops are golden brown and feel firm to the touch. Let muffins cool in the pan 5 minutes, then turn them out to cool on a wire rack. Serve the muffins warm or at room temperature.

Karen’s Notes and Tips

  • If you don’t have fresh blueberries on hand, frozen berries work beautifully. Just measure them out and let them thaw for about 15 minutes.
  • I’ve successfully used fruit juice to soak the oats, but you can use your preferred type of dairy milk or plant-based milk (oat milk or almond milk are my preferences).
  • All-purpose flour or a gluten-free blend will work in this recipe. You can also swap about 1/2 cup of the all-purpose for whole wheat flour.
  • Make these muffins gluten-free with your favorite store-bought gluten-free flour blend.
  • Muffins will stay fresh 1-2 days at room temperature.
  • Freeze the baked muffins and store them up to one month. Thaw them on the kitchen counter or overnight in the refrigerator.

    I have been searching for a healthier/ cheaper alternative to box mix muffins for months now. I have found it! These muffins are fantastic, and they’re even easier to make than the box mix I always made. My family loves oats so much that I sub ⅓ of the flour with oat flour (super easy to make). I subbed the sugar topping for streusel and the recipe for that is on this site! It’s called, “Big Blueberry streusel muffins.” That is by far the best homemade streusel recipe I have ever tasted, and I will use it for every muffin recipe from now on. I’ve made these a couple times and everyone in my house loves them so much. Can’t wait to try more recipes from this site.

    amazing muffins. I made with gluten free flour and they were amazing. i just a fresh batch with regular flour. Just as yummy. thank you!

  3. Has anyone tried to sub honey for the granulated sugar? If so, how did it go and what amount do you recommend? Trying not to send my kiddos off to school with simple sugars in their bellies. X

    1. Hi Emily – I have not tested this recipe with honey. Honey is much sweeter than granulated sugar (2 or 3 times by volume). So, if you’d like to cut down on sugar, try using 1/4 cup honey (or pure maple syrup) instead of the granulated sugar, adding and mixing it in step 2 with the oats and liquid. If you add up to 1/2 cup honey for a sweeter muffin, reduce the liquid (juice, water or milk) to 1/4 cup.

  4. Soooo good and easy!
    But won’t use 2 cups of frozen next time…. Too many.
    Didn’t have the sugar for topping so used a bit of finely shredded coconut….delish.
    Thanks for recipe 😁

    I make this recipe with extra berries and cinnamon sugar on top. It’s my favorite muffin recipe.

  7. 5 stars
    Super easy and quick! I used Gluten Free flour and almond milk.

    1. Thanks for sharing your substitutions – I’m glad to hear you enjoyed the muffins!

  8. 5 stars
    Easy yummy muffins! I added a bit of flax as I add flax to most breads and soups. Will definitely make again.

    These muffins turned out beautiful! I replaced a half cup of the flour with whole-wheat flour and added 2 tablespoons of lemon juice and skipped the sugar on top. So yummy!!

  10. Thanks Karen,
    I’m gluten intolerant and “we” suspect our grandson is. So this is a perfect recipe for both of us. The mixture holds up well (not crumbly) and has a good flavour.

    1. That’s great to hear Loraine! I know it can be hard to find recipes that make everyone happy.

  11. How would you make this into a gluten free recipe? I have a friend who cannot have anything containing gluten

    1. I haven’t tested these muffins with gluten-free flour, but will get back to you soon and let you know!

    2. Hi Susanne- I just baked a batch of the muffins using King Arthur gluten-free flour and they came out perfect.

  12. Delicious! I didn’t have cane sugar, as such, so I ground some turbinado sugar in my coffee grinder. Didn’t have wh-wh pastry flour, either, so I used 1/2 c graham flour + 1 c all-purpose flour. This’ll be my default blueberry muffin recipe now — thanks!

    1. Shannon – good for you. Your substitutions sound tasty and creative. I’m so glad to hear you like the recipe!

  13. I really shouldn’t be reading such yummy recipes in the early morning…it makes me want some of those great muffins! With oats…my favourite secret ingredient!

  14. I love muffins-walking that line between dessert and bread. These look good and good for you!

  15. Beautiful muffins! Hope you’re having a good summer.

  16. I love that sparkle of turbinado on top of muffins!

  17. Those look and sound delicious, and I am not even a muffin fan. I might even make them myself!
